SELF-SPACIIIG SIIIIIGLE.

-Application filed October 17, 1921. Serial No. 22,359.

My invention relates to shingles made preferably out of composition roofing material. cut from a continuous piece in such manner that there is not only no loss due to the cutting, and also no loss'of material due to the l of the shingles. But the shingles issue with spacing projections that cause them, when laid, to cover an enlarged roof and develop channels between. them; the projections on the one part and the complementary recesses on the other part beingfornied on-lines thaticonverge toward the edge which separates the shingles so that the projection will be arrested by the mouth of the recess; and preferably the projection being arorided witl a reduced end that intrudes sufficiently within the month of the recess to assist in relating the shi' les lengthwise; the lastnamed feature being in some instances further developed so as to provide a dovetail interlock between the said-reduced portion of the spacing pr jectionand the mouth of the recess. This is accomplished by so cutting shinglesfl'rom the roofing sheet that the projection on one side of the shingle is cut from the adjacent side of the opposite shingle, so that when separated a recess or vacant space will be left by the removal of the project-ion attached to the adjacent shingle, thus each shingle having a projection on one side and a recess on the opposite side. These projections are shaped similar to arrow heads having the apices of the heads out about the center of the arrow, the drawing being made along conventional lines. However, the projection and the recess need not be confined to this particular design, but this is the preferred form.

Heretofore self-spacing shingles that were cut from the material without loss have all been laid close together, abutting each other,

' so that there was loss of material or more material required than when laying individual standard shingles spaced inch apart. In my invention, by cutting the pro jection from the'body of the adjacent shingle and then setting the shingles against the outside walls of the recess of the shingle from which the projection has been cut, I do not require any more material than is required by laying shingles spaced inch apart, yet I produce a shingle which is self registering, so that it is accurately selfspacing both vertically and horizontally.

The projections may also be made in such a manner that a section ofthe projection will interlock in the recess if it is so desired. I In the drawing herewith I have shown in ure l a roofing sheet from which shingles are cut. I have shown the line of cutting which of course will be the line of separation.

In Figure 2 I show an individual shingle having a projection and a recess.

In 1 igure 3 is shown two adjacent shingles, spaced apart through thecooperation of the projection and the recess.

1 are 4- illustrates the appearance of the roofing when laid.

In the drawing Figure 1,a-V represents'the material from which the shingles are c i? represents the line of separation, c ro esenis the base of the arrow formation, which is in a manner a projection from the base of the triangular formation of the arrow head minus the apex. It need not be necessary to have the projection at all times the same formation and design of the recess, as part of the projection may be out off, while the recess would take the shape of the original cutting. I

I do not wish to be confined to any method of structure as long as the results accomplished are as herein set forth.

cZ represents the wings of the base of the triangular part of the arrow.

In Figure 2 the individual self-spacing shingle is more clearly set forth, and at the right of the shingle 0 illustrates the recess left after removing the projection In this figure is also shown the material a, the lines of separation b, the base of the projection 0, (id the wings of the arrow, 7 represents the projection itself and 6 illustrates the recess left by removal of the projection 7.

In Figure 3 two cooperating shingles are shown in which the projection 7 having the base part 0 of the projection resting within the outside walls of the recess e, and the shouldersor base of the arrow resting against the outer edge of the shingle. It will readily be understood that thebase of the arrow 0 may be cut the same as the wings of the triangular part of the arrow dd, as shown at 00 in f at Figure 1. In this case the base 0 shown in Figure 3 would cooperate with the recess 6, would interlock with the outside Walls gg of the recess 6,

inasmuch as the base portion 00 would be the same form as the outside walls 99 of the recess c.

This will allow of the spacing of the shingles horizontally, provided by the wings of the arrow (id, and the spacing of the shingles vertically provided by the base of the arrow 0, Figure 8, or 00 Figure 1, depending upon how the base is formed.

Figure 4 simply illustrates a series of 00- operating shingles laid upon the root, and their appearance after being covered up by overlying shingles.

I wish it to be understood in the above description and the drawings shown that the right is reseved to any modification of this structure and wherever self-spacing shingles are produced, where the material required will be no more than that required by the individual standard shingles after being spaced apart.

Having thus described my invention, what I claim and desire to secure by Letters Patent is v 1. Shingles adapted to be laid in rows; one shingle having a recess, and another shingle having a projection constructed to enter said recess and engage the shingles against relative longitudinal movement, said projection having an enlarged portion that arrests the intrusion of said projection into said recess. a

2. Shingles adapted to be laid in rows with their edges in spaced position; one shingle being constructed with a recess e" opens at its oppose'dedge and the other shingle having a projection constructed with a reduced portion adapted to enter the opening of the recess at such edge and with an enlarged portion that arrests the intrusion of the projection into the recess before duced portion adapted to enter theopening of the recess. 7 j

4. Shingles, adapted to be laid in rows with edges opposed, constructed at their opposing edges, respectively with adove-tail recess presentlng a reduced opening at .the edge of the shingle, and with a dove-tail pro ection having upon its outeredge a. reduced extension corresponding in dimension to the I reduced opening of the recess.

VSigned at Chicago, Illinois, this fourteenth day of October 1921.
